The American Kennel Club recognizes about 200 sort-of-different dog breeds. (The Belgian sheepdog and its sort-of-distant cousins, the Malinois and the Tervuren, are three separate breeds in AKC reckoning; in Belgium, they’re three varieties of the same dog.) There are lots of other breeds that have yet to receive AKC attention. And there are breeds that will never be seen again, by AKC or anyone else:
Are any current breeds marked for extinction? Surely not deliberately so; but, say, the otterhound — pretty much nobody hunts otters anymore — is fairly unemployable.
